Abstract
A method for for signaling high-level information in image and video coding is provided. A video decoder receives data from a bitstream to be decoded as a current picture of a video. The video decoder parses a picture header of the current picture that includes a set of one or more slice information syntax elements in the picture header for indicating presence of one or more types of slices that are present in the current picture. The video decoder reconstructs the slices of the current picture by using the set of slice information syntax elements.
